Question

The ordered pair (5,1) satisfies which of the following equations?

A. 2x-2y=5

B. 2x+3y=13

C. 2x-y=2

D. 2x+2y=11

Answer 1

In order for the ordered pair (5, 1) to satisfy an equation, the result must be correct when you substitute 5 for x and 1 for y in an equation..

For choice B: 2x + 3y =13

2*5 + 3*1 = 10 + 3 = 13

Therefore choice B is the correct equation.

Be sure to check all the choices. In this case, (5,1) is not a valid solution for the equations in choice A, C, or D.
